To prepare 2-methyl-3-furanylacetone, there are various ways to synthesize it.
First, furfural can be used. Furfural is first reduced to furfuryl alcohol through suitable reducing agents, such as sodium borohydride. In this process, the amount of sodium borohydride, reaction temperature and reaction time need to be precisely controlled. After obtaining furfuryl alcohol, a specific catalyst, such as sulfuric acid, is used to catalyze its dehydration and cyclization to generate 2-methylfuran. At this step, the concentration of the catalyst, the reaction time and temperature have a great influence on the purity and yield of the product. Subsequently, 2-methylfuran is acylated with a suitable acylating reagent, such as acetyl chloride, under the action of catalysts such as aluminum trichloride, to obtain 2-methyl-3-furanylacetone. In this route, the conditions of each step of the reaction need to be carefully adjusted to improve the yield and purity of the target product.
Second, 2-methylfuran can also be used as a starting material. First, 2-methylfuran and formaldehyde are hydroxymethylated in the presence of an alkaline catalyst such as sodium hydroxide to generate 2-methyl-5-hydroxymethylfuran. This step requires attention to the strength and dosage of the basic catalyst to avoid overreaction. After that, 2-methyl-5-hydroxymethylfuran is oxidized to 2-methyl-5-formylfuran. Commonly used oxidizing agents include manganese dioxide, and the conditions of the oxidation process need to be carefully controlled. Finally, 2-methyl-5-formylfuran is nucleophilic with methyl Grignard reagents, such as methyl magnesium bromide, and then properly treated to obtain 2-methyl-3-furanylacetone. This route is relatively complicated, but each step has its own key point, which is related to the success or failure of the overall synthesis.
Furthermore, other related compounds can be explored as starting materials, and the structure of the target molecule can be gradually constructed through a series of functional group transformation and reaction. However, no matter what kind of synthesis path is selected, it is necessary to study the reaction mechanism in depth and precisely control the reaction conditions in order to achieve high-efficiency and high-purity synthesis of 2-methyl-3-furanylacetone.

There are 2-methyl-3-furanyl acetone today, and it is difficult to determine the price range on the market. The price of the cover often changes for many reasons.
First, it is about purity. If its purity is high and almost flawless, it is suitable for high-end pharmaceutical research and development, high-end fragrance preparation, etc., the price will be high, or it can reach hundreds of gold per gram. If the purity is slightly lower, it will only be used as ordinary chemical raw materials, and the price will drop sharply, or only a few tens of gold per gram.
Second, it depends on the situation of supply and demand. If for a while, the demand for it in the pharmaceutical industry, the fragrance industry, etc. increases sharply, and the output is limited, and the supply is in short supply, the price will rise. On the contrary, if the supply exceeds the demand, the merchant must reduce the price in order to sell the goods quickly, and the price may drop significantly.
Third, the raw materials and production methods also have an impact. If the raw materials for making this 2-methyl-3-furanylacetone are rare and rare, or the production method is complicated, it requires a lot of manpower, material resources, and financial resources. The cost is high, and the price is not low. If the raw materials are easily available, the production method is simple, and the cost is reduced, the price will also drop.
Fourth, market competition is related to price. There are many people in the market, competing for profits with each other, competing for customers, or reducing prices. If there are few merchants, they are almost monopolized, and the price is often high.
Generally speaking, the market price of 2-methyl-3-furanoacetone varies from tens of gold to hundreds of gold per gram, and the specific amount must be determined according to the actual situation at that time.
